Txheej txheem cej luam
Cov khoom no yog tsim rau sab hauv tsev 33kV, 35kV, 36kV, AC system metering thiab tiv thaiv.
Cov khoom siv tuaj yeem siv nws tus kheej los yog nruab rau hauv cov khoom ua tiav ntawm cov txee thiab cov chaw ua haujlwm.
Tam sim no transformer txais high-voltage epoxy resin, imported silicon steel ntawv hlau tub ntxhais, lub winding txais high-insulation enameled tooj liab hlau, thiab winding thiab hlau core yog kho nrog high-zoo semiconductor shielding ntawv.
Tus qauv tsim
Lub hauv paus qauv ntawm voltage transformer yog heev zoo ib yam li cov transformer.Nws kuj muaj ob lub windings, ib qho yog hu ua thawj winding thiab lwm qhov yog hu ua theem nrab winding.Ob leeg windings yog mounted los yog raug mob nyob ib ncig ntawm lub hlau core.Muaj kev rwb thaiv tsev ntawm ob lub windings thiab nruab nrab ntawm cov windings thiab cov tub ntxhais hlau, kom muaj hluav taws xob sib cais ntawm ob lub windings thiab nruab nrab ntawm cov windings thiab cov tub ntxhais hlau.Thaum lub tshuab hluav taws xob hloov hluav taws xob ua haujlwm, thawj winding N1 txuas nrog rau txoj kab sib txuas, thiab qhov thib ob winding N2 txuas nrog lub twj paj nruag lossis relay nyob rau hauv parallel.Yog li ntawd, thaum ntsuas qhov hluav taws xob ntawm cov kab hluav taws xob high-voltage, txawm hais tias thawj qhov hluav taws xob yog siab, qhov thib ob yog qhov tsawg-voltage, uas tuaj yeem ua kom muaj kev nyab xeeb ntawm cov neeg siv khoom thiab cov cuab yeej siv.
Cov kev ceev faj
1. Ua ntej lub tshuab hluav taws xob hluav taws xob tau muab tso rau hauv kev ua haujlwm, kev sim thiab tshuaj xyuas yuav tsum tau ua raws li cov khoom tau teev tseg hauv cov kev cai.Piv txwv li, ntsuas polarity, kev sib txuas pab pawg, co rwb thaiv tsev, nuclear theem sib lawv liag, thiab lwm yam.
2. Kev xaim ntawm qhov hluav taws xob hloov hluav taws xob yuav tsum xyuas kom meej nws qhov tseeb.Tus thawj winding yuav tsum tau txuas nrog nyob rau hauv parallel nrog lub Circuit Court nyob rau hauv kev ntsuam xyuas, thiab lub thib ob winding yuav tsum tau kev cob cog rua nyob rau hauv parallel nrog lub voltage coil ntawm kev cob cog rua ntsuas ntsuas, relay tiv thaiv ntaus ntawv los yog tsis siv neeg ntaus ntawv.Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them rau qhov tseeb ntawm polarity..
3. Lub peev xwm ntawm lub load txuas nrog rau sab thib ob ntawm lub tshuab hluav taws xob hloov hluav taws xob yuav tsum tsim nyog, thiab cov khoom txuas nrog rau sab thib ob ntawm lub tshuab hluav taws xob hloov hluav taws xob yuav tsum tsis txhob tshaj nws cov peev txheej, txwv tsis pub, qhov yuam kev ntawm lub transformer yuav nce, thiab nws yog qhov nyuaj kom ua tiav qhov tseeb ntawm qhov ntsuas.
4. Tsis pub luv luv Circuit Court nyob rau theem nrab ntawm qhov voltage transformer.Txij li thaum lub impedance nyob rau hauv lub voltage transformer yog heev me me, yog hais tias lub thib ob Circuit Court yog luv luv, ib tug loj tam sim no yuav tshwm sim, uas yuav ua rau lub thib ob cov khoom puas thiab txawm muaj kev ruaj ntseg ntawm tus kheej.Lub tshuab hluav taws xob hloov hluav taws xob tuaj yeem nruab nrog lub fuse nyob rau sab thib ob los tiv thaiv nws tus kheej los ntawm kev puas tsuaj los ntawm lub voj voog luv luv ntawm ob sab.Yog tias ua tau, fuses yuav tsum tau muab tso rau ntawm thawj sab los tiv thaiv cov hluav taws xob hluav taws xob hluav taws xob los ntawm kev ua phem rau kev nyab xeeb ntawm thawj qhov system vim qhov tsis ua haujlwm ntawm lub tshuab hluav taws xob hluav taws xob los yog cov hlau lead.
5. Txhawm rau kom muaj kev nyab xeeb ntawm tib neeg thaum kov cov ntsuas ntsuas thiab cov relays, qhov thib ob winding ntawm voltage transformer yuav tsum tau grounded ntawm ib qho chaw.Vim hais tias tom qab grounding, thaum lub rwb thaiv tsev ntawm lub hauv paus thiab theem nrab windings puas lawm, nws muaj peev xwm tiv thaiv tau lub siab voltage ntawm lub twj paj nruag thiab relay los ntawm kev ua phem rau tus kheej kev nyab xeeb.
6. luv luv Circuit Court yog kiag li tsis tso cai nyob rau theem nrab ntawm lub voltage transformer.
